A method of operating a modulated continuous-wave radar system at least includes steps of transmitting, with a modulation frequency, a plurality of n modulated continuous radar waves that represent mutually orthogonal codes towards a scene with a potential object to be detected, wherein the transmitted modulated continuous radar waves of the plurality of modulated continuous radar waves are consecutively transmitted with a constant time lag given by one nth of a period of the modulation frequency; digitally converting a plurality of reflected and received radar signals with a sampling rate that is equal to the modulation frequency; decoding individual range information for each received radar signal; and determining a range between the radar system and the object on the basis of the decoded individual range information.
